Abstract
Se proporciona un metodo para purificar un polimero recuperado. El método involucra obtener polimero recuperado, al ponerlo en contacto con un primer solvente fluido para producir un polimero recuperado extraido despues de disolver el polimero recuperado extraido en un solvente para producir una primera solucion que comprende polimero y contaminantes suspendidos. La primera solucion se sedimenta para producir una segunda solucion que comprende polimero y contaminantes restantes. La segunda solucion se purifica al poner en contacto la segunda solucion con medio solido para producir una tercera solucion que comprende polimero mas puro. Finalmente, el polimero mas puro se separa de la tercera solucion.
